Features and Benefits
Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high-speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
Multilayer Titanium Aluminum Nitride (TiAlN) is a blended coating that is more efficient than TIN. It offers a high level of wear resistance at higher cutting speeds and used on high alloy steels and cast iron.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
